I've been reading reviews on this forum and listening to my newly arrived 105 and just wanted to chime in regarding a few grumbles about the unit sounding too thin. After some listening and comparing to my older BDP-93, yes (with the 105) the bass is tighter and less commandeering than in the 93 but overall, the 105 is so much easier to listen to. Though I do like that bass heavy sound just for sheer slam effect it's a bit unrealistic. Most real instruments, like upright bass and kick drums don't rumble the house when played, with the exception of say, heavily amplified bass instruments. .......still, it's fun to listen to. I think that the 105 is more realistic in this respect.....
Be that as it may with regards to the 93, I seem to have to strain or really concentrate more to separate instruments out of the mix. Fine detail sounds a bit smeared with the 93. With the 105, I feel me ears relax, everything is well defined, no fatigue. So I'll take the 105 over this any day.
I had a revelation the other day.....I own a pair of Von Schweikert VR-33's. An interesting thing about these speakers is that they have a rear firing 10" woofer. Distance from the wall to the back of the speaker determines bass amplitude. BTW, these speakers are designed to sit close to the wall. One can move them in and out from the wall to suit their bass needs. I went from a 10" placement down to about 5" and things are sounding better. I think I might continue to fine tune this as the difference of an inch or two placement makes significant difference in bass response. There is a lot of discussion on placement of these speakers on the Von Schweikert forum
Not trying to get off topic but I thought that perhaps others unhappy with the bass response might benefit by speaker placement experimentation.
